Application filed January 16, 1905. Serial No. 241,201.

To all whom it may concern:

Be it known that I, ELIAS HAIMAN, acitizen of the United States,residing at Cleveland, in the county of (Juyahoga and State of Ohio,have invented certain new and useful Improvements in Cultivators; and Ido declare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same. Y

My invention relates to improvements in cultivators; andthe inventionconsists in the construction, combination, and arrangement of partsthereof all substantially as shown and described, and particularlypointed out in the claims. I

In the accompanying drawings, Figure 1 is a perspective view of acultivator comprising thereof.

my improvements, and the remaining figures are enlarged views of detailsand sections Fig. 2isa side elevation of a section of the central'bar orbeam with my improved mechanism shown thereon in elevation. Fig. '3 is aplan view of 'Fig. 2,and Fig. 4 is aperspective view of. the two partsof my improved attachment seen together in Figs. 2 and 3 and separatedto disclose the details of their construction. FigsI 5 and 6 are endelevations of Fig. 2; and Fig. 7' is a crosssection corresponding toline a: aflFig. 2, looking to the right.

The idea of the invention as thus disclosed in the several views is toobtain a positive and convenient adjustment of the side bars of thecultivator in respect to the central bar according to the width to becovered at any given time, the said mechanism b'eing within easy reachthrough a suitable lever whereby the operator can in a moment.

adjust the side bars to any desired width within the range of adjustmentprovided for and when adj ustmentis efiected rigidly fix the said barsin that relation, all as will'more clearly.

appear in the details of description.

Iam aware, of course, that'various devices have been made and usedhaving the same gen eral object in view and that numerous patentsstruction is that it is exceedingly simple in itself and economical inmanufacture and especially efiective and advantageous in use aml thatsofar as I know and believe it is essentially new.

Referring again to the drawings, A represents the central tooth-bar ofthe. cultivator, and C the respective side bars thereof. These bars areequipped with cultivator-teeth a all around, which may be rigid withsaid bars or have standards C of their own pivoted and adjustable uponsaid bars to give more or less pitch to theteeth, as may be desired, and

either an integral or a pivoted construction may be used.

otally'engaged upon box B, and the two are adapted to slide together onbar A to effect the various adjustments of the side bars.

The box B is formed with right angled flanges d and d along its upperand lower edges, adapted to lap over the edges and side of bar A, topand bottom, and to confine the said section B upon said barindependently of the pivoted part D. In this sense, therefore, th-ebox Bis an independent member remaining permanently in a slidable position onbar A, and it can be conveniently placed upon said bar, over the rearend thereof, before the rear cultivator-standard O is placed thereon.The

side bars O are connected with this box by upper and lower links 2 and3, respectively, which I ver G,' whereby the position of the box is.con-

trolled. The pivoted side wing or looking member D is provided withshort hinge-arms 6, having right-angled pivot-points 7 adapted to engagein the sockets or bearings 8 in the top ofsection B above and over thebeam A in this instance, and the said arms are presumably engaged -inthesesockets before the parts are assembled upon bar A, so as to bepermanently confined therein. .These arms tion.

andtheir pivot-points 7 in said sockets afford a free lateral rotationor swinging movement to the part D, so that it'may be rotated or turnedaway from the bar A to disengage therefrom when adjustment is to beeffected and which will automatically spring or drop back against saidbar again when adjustment has been made and the box is to be locked inworking position. To these ends the said pivoted locking member D isprovided with a series of holes 9 or their equivalent between its endsat suitableintervals apart, which are adapted to engage with the pin,projection,

or lug 10 on the side of bar A. Preferably this lug or pin is made aseparate part fixed in bar A; but it might be formed in or from the baritself and is treated herein as a part of the bar. Said pin has atapered body set into a correspondingly-tapered seat and is upset on itsopposite end to fasten it in the bar, which makes a convenient method ofmanufacture and a desirable locking projection for the box. The saidpivoted part D is designed normally to rest against the side of bar A ina locked position by engaging one of its holes over lug or pin 10, andit is held in such position by a spring 12, which is confined betweencorresponding lateral projections 18 and 14: on the two parts B and D.This spring comes on the opposite side from the pivoted locking memberor wing D and the pivots thereof on the side of box B, so that itstendency is to hold part D in locked position, and adjustment can onlybe effected when the said part or member D has been carried or swunglaterally upon .its pivots a suflicient distance to disengage it frompin 10. This is accomplished by means of a crank-lever g at the top ofmain lever G, which is connected by a wire or its equivalent g with thelateral projection 15 at. the top and edge of the said member or wing D.When such disengagement is effected by these or equivalent means, the.box as a whole, with wing D, may be moved along by lever Gr upon thebeam A back or forth, as may be required, and when lever g is releasedand part D drops back to engaging position it is easy to move it intoconnection with the nearest hole 9 upon the lug 10, if this has notalready occurred, and thislocks the parts again in working posi- Anysuitable means may be provided as a fulcrum for lever G; but in thisinstance a link 16, connected'with the cross-bar 17 on thehandle-supporting braces 18, serve as such fulcrum.

It will be noticed that the bearings 8 for pivot or hinge projections 7are raised portions in the overhanging upper right-angled edge cl of thebox B and that engagement with said bearings or sockets can only be madefrom beneath before the box is placed on the central bar, and when onboth parts B and D are permanently engaged on said bar. It will also benoticed that the said locking member D has only such width that it willcome be tween the edges d and d of box B, and the said box has thereforean open side to receive the said member D and which enables it to slidewithout contacting with projection 10.

Obviously the openings or holes in the locking member D might extend tothe bottom edge thereof, which would give it the appearance of arack-bar; but this would be equivalent only to what is shown, and saidmember or part D might be as much shorter as a more limited range ofadjustment would suggest.

YVhat I claim is- 1. In cultivators, a central and side bar, a slidablemember on the central bar and a locking device pivoted thereon, saidcentral bar provided with a projection at its side to engage saidlocking device therewith, a controlling-lever for said slidable memberand means thereon operatively connected with said locking device torelease the same from locking engagement.

2. In cultivators, a central bar having a fixed lateral projection atits side, side bars and meansto fix the working position of the sidebars in respect to the central bar comprising a device slidable on thecentral bar, links conmeeting said device with the said side bars and alock for said device pivoted thereon and constructed to engageadjustably with the said lateral projection on the central bar.

3. In cultivators, central and side bars and means to adjustably fix therelations of the side bars comprising a box slidable on the central barand links connecting said box with the side bars, said central barhaving a lateral projection at its side, and a lock for said box.provided with a series of openings adapted to engage with saidprojection.

4.. Acultivator having central and sidebars, means for controlling theposition of side bars consisting of a box on the central beam having anopen side lengthwise, a locking device for said box in said open sideand the said central bar constructed at'its side to engage said lockingdevice.

5.
